VACUUM Application led March 8,

To all whom z't-may concern:

Be it known'thatI, BnNNm'r L. CALLA- HAN, citizen of the United States, residin at Abilene, in the county of Dickinson an State of Kansas, have invented new and useful Improvements -in .Vacuum Cleaners, of which the following is a specification.

This invention relates to vacuum cleanin devices, and morey particularly to improved means for alternately beating and cleaning a ioor covering, such as a carpet, rug or the like, whereby the dirt or dust collected on the carpet will be loosened by the beater and easilyv removed by the sweeper when the cleaner is brought into contact with the carpet.

Astantially along the line 3-3 of Figu One of the essential features embraced in the present development consists in removably securing the sweeper or brushes to the ends of the beater in such a 4manner as to permit the sweeper to be adjusted laterally relative tothe beater and easily removable therefrom when worn out through usage.

Referring to the drawing, wherein is'dis- `closed a preferred embodiment of the invention:

Figure 1 is a sectional view of `a vacuum cleaner showing my invention attached thereto.

Fi re 2 is a sectional view taken substantially along the line 2-2 of Figure 1.

Figure 3 is a sectional view taken subrev 2.

Figure 4 is a detail end view of one of the beaters.

Referring to the drawings, wherein like numerals indicate like parts in the various views, 10 denotes a vacuum cleaner casing of any suitable form and construction, which has its nozzle portion 11 provided with a lon itudinal opening 12. A motor 13 is pre erably mounted on the casing lO, and is provided with a vertical drive shaft le, which projects' into the casing 10, and has secured to its lower end a pulley 15, that' is operatively connected to a corresponding pulley 16 on the shaft 17 by the belt 18.

The ends of the shaft 17 are preferably journalled to the caps 18, which are provided with serrated end portions 19 arranged to t in the bearings 20 and may be secured thereto by any suitable means, such as the set screws 21, as shown in dotted lines in Figure V2.

A beater element composed of a rod 22 is preferably positioned on each side of the CLEANER.

pulley 16, and has itsmajorportion arranged substantially parallel with the axis of the shaft 17, and its threaded ends 23 bent laterally to extend through suitable openings formed in the shaft 17 and rojecting an appreciable distance beyond tlie sides of said'shaft.

Each of the ends 23 of the beater is provided with a recess 24, which is adapted to receive the ends of a suitable twisted wire brush 25. The projection of the ends 23 through' the shaft 17 is preferably regulated by means of the nuts 26 and 27, which are threadedly secured to the ends 23. The ends of the twisted wire 25 are fixedly secured in the recesses 24 by nuts 28 and 29 as clearly shown in Figure 3. Instead of the wire brushes 25, any other suitable sweeping means provided with cleaning instrmentalities, such as bristles or the like, may be employed.

By reason of the present construction, it-

will be seen that when the motor 13 is turned on, rotation is imparted to the shaft 17, which causes {the beater 22 and the cleaner or brushes 25 to be brou ht alternatively into contactv with the oor covering.

The dirt or dust formed on the carpet is loosened by the action of the beaters 22 and carried by the lbrushes 25 into the nozzle 11,

where it is conducted by the suction fan 30,

that is secured to the shaft 14, to the discharge port 31, to which may be connected any suitable dust receiving receptacle, (not shown).

The durability of the brushes 25 is greatly enhanced by means of the particuiar formation of the beaters 22, since when the portion of the brushes 25 that are brought into contact with the floor coveringhave become worn through usage, the spindles of the brush may be turned. by-loosening the nuts 28 so as to present a new sweeping surface to the loor or they may, by the adjustment of the `nuts 26 and 27, be disposed farther away from the shaft 17 It is to be understood that the present construction is merely illustrative, of a preferred embodiment of' my invention, and that mechanical changes may be made. therein without departing from the spirit of the invention and the scope of the appended claims.

' 1. .et @teaser of the class described eene prising a nozzle, a shaft journalled in said nozzle, a beaterI having a portion extending substantially parallel to said shaft and a portion projecting beyond the opposite side of the shaft, and a sweeper secured to the projected portion of the beater.

2. A cleaner of the class described comprising a nozzle, a shaft journalled in said nozzle, a beater element having a portion extending substantially parallel with said shaft and -its ends bent to project through the shaft, a sweeper connected to said ends, and means for adjusting said beater element and sweeper relative to said shaft.

3. A cleaner of the class described comprising a nozzle, a shaft journalled in said nozzle, a beater element having its ends bent, so as ,to extend through said shaft, a sweeper' secured to the ends of said beater element, and means for rotating said shaft to alternately beat and sweep a oor covering.

4. The combination with a cleaner having an inlet mouth, of a shaft joui-nailed in said mouth, a beater having a portion thereof arranged substantially parallel with said shaft and its ends bent to extend through and beyond said shaft, a sweeper secured to the ends. of said beater, and means for adjusting the beater and sweeper relative to said shaft.

5. rlhe combination with a cleaner having a suction nozzle, of a shaft journalled in said nozzle, a beater element having a portion thereof arranged substantially parallel with the shaft and its ends bent to extend through said shaft, a sweeper secured to the ends of said beater element, means on said element to adjust the sweeper relative to said shaft, and means for' rotating said shaft.

y6. The combination with a cleaner having a suction nozzle, of a shaft, a beater element having its major portion arranged substantially parallel to said shaft, and its ends bent to extend laterally through said shaft, a recess in each of said ends, a sweeper secured in said recesses, and disposed in substantial parallelism with the major portion of said beating element, and means for rotating said shaf 7. The combination with a cleaner having 'a suction nozzle, of a shaft, a beater elementhaving its major portion arranged substantially parallel to said shaft, and its ends bent to extend laterally through said shaft, a recess in each of said ends, a sweeper secured in said recesses, and disposed in substantial parallelism with the major portion-of said beating element, means for adjusting said beater element and said swee-per relative to said shaft, and means for rotating said shaft.

\ In testimony whereof I have hereunto set my hand.
